  Cyanoacetamides (IV): Versatile One-Pot Route to 2-Quinoline-3-carboxamides

  摘要：

  Cyanoacetic acid derivatives are the starting materials for a plethora of multicomponent reaction (MCR) scaffolds. Herein, we describe scope of a valuable general protocol for the synthesis of arrays of 2-aminoquinoline-3-carboxamides from cyanoacetamides and 2-aminobenzaldehydes or heterocyclic derivatives via a Friedlander reaction variation. In many cases, the reactions involve a very convenient work up by simple precipitation and filtration. More than 40 new products are described. We foresee our protocol and the resulting derivatives becoming very valuable to greatly expanding the scaffold space of cyanoacetamide derivatives.

• SAR Study and Molecular Mechanism Investigation of Novel Naphthoquinone-furan-2-cyanoacryloyl Hybrids with Antitumor Activity

  A series of novel naphthoquinone-furan-2-cyanoacryloyl hybrids were designed; they were synthesized and preliminarily evaluated for their anti-proliferative activities in vitro against several cancer cell lines and normal cells. The most potent compound, 5c, inhibited the proliferation of HeLa cells (IC50 value of 3.10 ± 0.02 μM) and colony survival, and it induced apoptosis while having relatively weaker effects on normal cells. Compound 5c also triggered ROS generation and accumulation, thus partially contributing to the observed cell apoptosis. A Western blotting analysis demonstrated that compound 5c inhibited the phosphorylation of STAT3. Furthermore, a biolayer interferometry (BLI) analysis confirmed that compound 5c had a direct effect on STAT3, with a KD value of 13.0 μM. Molecular docking showed that 5c specifically occupied the subpockets in the SH2 domain, thereby blocking the whole transmission signaling process. Overall, this study provides an important structural reference for the development of effective antitumor agents.

  本研究设计了一系列新型萘醌-呋喃-2-氰基丙烯酰杂环化合物；合成了这些化合物，并初步评估了它们在体外对几种癌细胞系和正常细胞的抗增殖活性。最有效的化合物 5c 抑制了 HeLa 细胞的增殖（IC50 值为 3.10 ± 0.02 μM）和集落存活，并诱导细胞凋亡，而对正常细胞的影响相对较弱。化合物 5c 还会引发 ROS 生成和积累，从而部分导致观察到的细胞凋亡。Western 印迹分析表明，化合物 5c 抑制了 STAT3 的磷酸化。此外，生物层干涉仪（BLI）分析证实，化合物 5c 对 STAT3 有直接作用，其 KD 值为 13.0 μM。分子对接显示，5c 特异性地占据了 SH2 结构域的子口袋，从而阻断了整个传输信号过程。总之，这项研究为开发有效的抗肿瘤药物提供了重要的结构参考。

  Macrophage migration inhibitory factor (MIF) is an essential signaling cytokine with a key role in the immune system. Binding of MIF to its molecular targets such as, among others, the cluster of differentiation 74 (CD74) receptor plays a key role in inflammatory diseases and cancer. Therefore, the identification of MIF binding compounds gained importance in drug discovery. In this study, we aim to discover novel MIF binding compounds by screening of a focused compound collection for inhibition of its tautomerase enzyme activity. Inspired by the known chromen-4-one inhibitor Orita-13, a focused collection of compounds with a chromene scaffold was screened for MIF binding. The library was synthesized using versatile cyanoacetamide chemistry to provide diversely substituted chromenes. The screening provided inhibitors with IC50's in the low micromolar range. Kinetic evaluation suggested that the inhibitors were reversible and did not bind in the binding pocket of the substrate. Thus, we discovered novel inhibitors of the MIF tautomerase activity, which may ultimately support the development of novel therapeutic agents against diseases in which MIF is involved.
